Description

FIELD OF THE INVENTION The invention relates to material transport, namely, step conveyors for transporting parts.

The famous conveyor belt includes a movable frame on wheels, moving along a fixed frame with inclined parts, over which spring-loaded arrows are mounted on racks, made in the form of single levers {I. During the movement of the frame in the directions and arrows, there is an alternation of the product to the specified inar.

The disadvantages of such a conveyor are low reliability due to the presence of spring-loaded arrows, limited pitch due to the size of the arrows, as well as inaccurate gripping of the parts being transported.

The closest pemeniie of the known ones is the steps. a conveyor including a driving movable frame mounted on rollers, with a lifting mechanism consisting of carriages with rollers and guides, and a fixed frame with travel stops of carriages 2.

Parts are transported when the moving frame moves along the carriage guides.

The disadvantage of the known conveyor is that the capture of parts occurs at the time of moving the roller

frame on the slope. of the guide carriage, as a result of which it is unremarkable to accurately determine the location of the gripped component on the movable frame.

The aim of the invention is to improve the accuracy of the capture of the transported parts in a certain position.

This goal is achieved by the fact that the guides are made in the form of shaped grooves on a driving movable frame for moving it along the carriage rollers with its simultaneous locking latch; carriage stroke.

FIG. 1 depicts the proposed coveyor (section A-A in FIG. 2); in fig. 2 shows a section .6-B in FIG. one.

The conveyor has a driving movable frame / with guides 2, made in the form of figured grooves, mounted on rollers 3, a lifting mechanism in the form of carriages 4 with rollers -5,} mounted in figured and directing 2, and not rotating on the frame. , chassis readers 7 and S of the carriages, with screwed on non-movable frame 6 and housing 9, drive 0.

Driving frame equipped

a pair of spring-loaded dogs L, sit. on a common axis 12 and providing

the raised position of the small nut 4 on the movable frame / while the conveyor is moving forward with part 13. On the axis .12, the stop 14 is rigidly fixed, turning the pawl 11 when driving over the screw 15 fixed to the housing 9. When the conveyor moves backward, the plunger 16 keeps the carriage in the lower position

The stepping conveyor operates as follows; in a way.

When moving the conveyor forward, the stop 14 hits the screw 15 and, turning the axis 12, lowers the paws //. Upon further movement of the movable frame 1 forward, the carriage 4 with the part 13 is fixed by a travel stop 8, while the guides 2 of the movable frame, made in the form of shaped grooves, move along the rollers 5 of the small nuts 4, lowering it vertically and leaving the part on the accumulator 10. In the lower position of the carriage 4 is fixed by the plunger 16.

During the reverse course of the conveyor, the carriage 4, reaching the travel stop 7, stops and with further movement of the movable frame, the back guides 2 move along the rollers 5, lifting the carriages 4 vertically upwards, while the carriages 4 receive the next part in a strictly defined position. Dogs 1-1 exit the carriages 4 and hold them in a raised position.

Then the cycle repeats.

Compared to the known, this step-by-step conveyor allows you to accurately capture a part in a certain position on the conveyor, which is necessary when using step conveyors in machine tool lines for feeding parts into the machine tools with their subsequent fixation.
